Dell XPS 10 Tablet May Get 'USB Not Recognized' Error

This article addresses an issue with certain USB devices triggering a 'USB Not Recognized' error on the Dell XPS 10 tablet.

Problem:Owners of the Dell XPS 10 tablet may see a 'USB Not Recognized' error when docking the tablet or booting the device.

Discussion:The XPS 10 keyboard dock has two USB ports and the tablet itself has a mini-USB port. These ports support a maximum of 500 milliamps each. This will support most mice and keyboards but is not sufficient for an optical drive or external hard drive that does not have its own power supply.

Solution:This is the design of the hardware. To clear the error, remove the device from the USB port. These devices will only work on the XPS 10 tablet if they have their own external power supply.
